Give your Traxxas Stampede a higher and wider stance using these 14mm clamp style aluminum wheel hexes (which allow the use of larger wheels and tire combos). Using high quality CNC machined aluminum, these clamp style aluminum wheel hexes lock down on the axle pins so losing pins is no longer a problem for your Traxxas electric Stampede. Aluminum hexes are also more durable and less likely to strip out, plus they provide a better fit to the wheel hex. We recommend 1/2" offset wheels for suspensoin clearance and wider stance.
